The effects of pH and temperature

The effects of pH and temperature were studied for an enzyme-catalyzed reaction. The following results were obtained.

a. How do (1) temperature and (2) pH affect the activity of this enzyme? lii your answer, include a discussion of the relationship between the structure and the function of this enzyme, as well as a discussion of how structure and function of enzymes are affected by temperature and pH.

b. Describe a controlled experiment that could have produced the data shown for either temperature or pH. Be sure to state the hypothesis that was tested here.
